title: Development of a scrotal vasocutaneous fistula producing viable spermatozoa 9 years after vasectomy.
abstract: OBJECTIVE
  To describe a case of scrotal vasocutaneous fistula discharging viable sperm.
  
  
  METHODS
  Case report.
  
  
  METHODS
  A hospital-based assisted conception center.
  
  
  METHODS
  A 37-year-old male presenting for fertility treatment 9 years after vasectomy with a scrotal vasocutaneous fistula that caused a painful, intermittently rupturing, subcutaneous cyst.
  
  
  METHODS
  Analysis of fistula discharge and planned fistula resection with vasovasostomy.
  
  
  METHODS
  Diagnostic semen analysis to determine presence or absence of spermatozoa in fistula discharge.
  
  
  RESULTS
  A very low concentration of live spermatozoa were identified in the fistula discharge.
  
  
  CONCLUSIONS
  We believe this is the first time that live spermatozoa, potentially suitable for assisted conception treatment using intracytoplasmic sperm injection have been identified in the discharge from a vasocutaneous fistula.
